Android: Itching Thumb is an Android task manager that displays running tasks (in a fashion similar to the alt-tab function in Windows) with live preview and enables gesture-based application launching.

The default Android task switcher simply displays recently run application icons—you can switch to the app you were using a moment ago by clicking the icon to return the focus to the app or starting it again. Itching Thumb actually shows you thumbnails of the active applications. In the space beneath the application previews you can swipe gestures to launch applications like G for Gmail or a C for your contacts list.

Check out the video above to see the application in action. Itching Thumb is a free application and works wherever Android does. Download a copy by scanning the QR code at right or searching for "Itching Thumb" in the Android marketplace. Thanks JEveryman!
